Motion graphics involve animating images to suit a video or film clip. A popular technique is key framing, where an object's properties are specified at certain points in time to be automatically altered between frames. Title sequences and interactive menus are common examples of motion graphics in films. They use techniques like zooming, panning, and objects moving left and right to create logos and introduce options. Stings and idents are other examples, using motion to advertise channels or grab attention. Compositing video can involve changing background footage to enhance a motion graphic overlay. The X-Men interactive menu analyzed uses distortion and rotation effects to introduce its menu buttons.
